摘要
传统经济理论普遍认为环境规制的实施会直接增加企业的整体生产成本,从而导致企业销售利润的降低。而“波特假说”则提出环境规制对企业整体效益的影响并不是单一负面的,环境技术创新提高的生产效益可能弥补治理污染所投入的成本,进而提升企业核心竞争力并可能获得高于预期的收益。本文构建了环境规制与企业技术创新之间关系的理论模型,利用2008~2019年我国30个主要省市的面板统计数据,实证检验了环境规制与技术创新间的门槛效应,并检验了“波特假说”。主要研究结论为:(1)就全国总体情况而言,环境规制与地区技术创新存在显著的正“U”型关系;(2)环境规制对地区技术创新的影响存在区域异质性,东、中地区较为显著,而西部地区则不显著;(3)环境规制对技术创新的作用依赖于区域经济发展水平,只有当经济发展水平达到一定门槛值以后,环境规制才能促进技术创新。
Classic economics generally believe that environmental regulation will directly increase the cost of enterprises'production,which will lead to the reduction of profit of enterprises.The“Porter Hypothesis”proposes that the impacts of environmental regulation on the enterprises are not just negative,and the benefits that may be generated through environmental technology innovation can even make up for the cost of pollution control,thus improving the core competitiveness of enterprises and obtaining higher profits than expected.This paper constructs a basic theoretical model of the relationship between environmental regulation and firm technological innovation.Using the panel statistical data of 30 major provinces in China from 2008 to 2019,the threshold effect between the two is empirically tested,and the“Porter Hypothesis”is also tested.The main conclusions are as follows:first,in terms of the overall situation of the country,environmental regulation has a significant positive“U”-shaped relationship with regional technological innovation;second,the impact of environmental regulation on regional technological innovation is different in different regions,the eastern and central regions are more significant,but the western regions are not significant;third,environmental regulation of the role of technology innovation depends on the regional economic development level of the threshold value,it is only when the level of economic development reaches a certain threshold value,environmental regulation can promote technology innovation.
